Realtime Integration Patterns

Build responsive pricing UIs today using polling strategies that can later be upgraded to true stream transport.

Polling Strategy

setInterval(async () => {
  const res = await fetch("/v1/cards/:id");
  const next = await res.json();
  updateIfPriceChanged(next);
}, 30_000);

Backoff + Stability Rules

  • Use 15-30s refresh for active watchlists, 60-120s for background pages.
  • Apply exponential backoff when HTTP `429` or `5xx` is returned.
  • Only re-render rows/cards whose price fields changed.
  • Debounce UI notifications so users are not spammed by micro-moves.

Preparing for Streams

Keep your client update pipeline transport-agnostic: one reducer for updates, multiple transport adapters (polling now, stream later).
